Terrain settings for a terrain generator that uses a raster DEM layer to build terrain.

Warning
This is not considered stable API, and may change in future QGIS releases. It is exposed to the Python bindings as a tech preview only.

Member Function Documentation

◆ clone()

QgsDemTerrainSettings * QgsDemTerrainSettings::clone ( ) const
finalvirtual

Returns a copy of the terrain settings.

Implements QgsAbstractTerrainSettings.

Definition at line 26 of file qgsdemterrainsettings.cpp.

◆ create()

QgsAbstractTerrainSettings * QgsDemTerrainSettings::create ( )
static

Creates a new instance of a QgsDemTerrainSettings object.

Definition at line 21 of file qgsdemterrainsettings.cpp.

◆ createTerrainGenerator()

std::unique_ptr< QgsTerrainGenerator > QgsDemTerrainSettings::createTerrainGenerator ( const Qgs3DRenderContext context) const
overridevirtual

Creates a new instance of a terrain generator which matches the terrain settings.

Note
Not available in Python bindings

Implements QgsAbstractTerrainSettings.

Definition at line 83 of file qgsdemterrainsettings.cpp.

◆ equals()

bool QgsDemTerrainSettings::equals ( const QgsAbstractTerrainSettings other) const
finalvirtual

Returns true if this settings is exactly equal to another other settings.

Implements QgsAbstractTerrainSettings.

Definition at line 69 of file qgsdemterrainsettings.cpp.

◆ layer()

QgsRasterLayer * QgsDemTerrainSettings::layer ( ) const

Returns the raster layer with elevation model to be used for terrain generation.

See also
setLayer()

Definition at line 99 of file qgsdemterrainsettings.cpp.

◆ readXml()

void QgsDemTerrainSettings::readXml ( const QDomElement &  element,
const QgsReadWriteContext context 
)
finalvirtual

Reads settings from a DOM element.

Subclasses should take care to call readCommonProperties() to read common properties from the element.

See also
resolveReferences()
writeXml()

Implements QgsAbstractTerrainSettings.

Definition at line 36 of file qgsdemterrainsettings.cpp.

◆ resolution()

int QgsDemTerrainSettings::resolution ( ) const
inline

Returns the resolution of the terrain (how many elevation samples are taken on one side of a terrain tile).

See also
resolution()

Definition at line 76 of file qgsdemterrainsettings.h.

◆ resolveReferences()

void QgsDemTerrainSettings::resolveReferences ( const QgsProject project)
finalvirtual

After reading settings from XML, resolves references to any layers in a project that have been read as layer IDs.

See also
readXml()

Reimplemented from QgsAbstractTerrainSettings.

Definition at line 64 of file qgsdemterrainsettings.cpp.

◆ setLayer()

void QgsDemTerrainSettings::setLayer ( QgsRasterLayer layer)

Sets the raster layer with elevation model to be used for terrain generation.

See also
layer()

Definition at line 94 of file qgsdemterrainsettings.cpp.

◆ setResolution()

void QgsDemTerrainSettings::setResolution ( int  resolution)
inline

Sets the resolution of the terrain (how many elevation samples are taken on one side of a terrain tile).

See also
resolution()

Definition at line 69 of file qgsdemterrainsettings.h.

◆ setSkirtHeight()

void QgsDemTerrainSettings::setSkirtHeight ( double  height)
inline

Sets the skirt height (in world units).

Skirts at the edges of terrain tiles help hide cracks between adjacent tiles.

See also
skirtHeight()

Definition at line 85 of file qgsdemterrainsettings.h.

◆ skirtHeight()

double QgsDemTerrainSettings::skirtHeight ( ) const
inline

Returns the skirt height (in world units).

Skirts at the edges of terrain tiles help hide cracks between adjacent tiles.

See also
setSkirtHeight()

Definition at line 94 of file qgsdemterrainsettings.h.

◆ type()

QString QgsDemTerrainSettings::type ( ) const
finalvirtual

Returns the unique type name for the terrain generator.

Implements QgsAbstractTerrainSettings.

Definition at line 31 of file qgsdemterrainsettings.cpp.

◆ writeXml()

void QgsDemTerrainSettings::writeXml ( QDomElement &  element,
const QgsReadWriteContext context 
) const
finalvirtual

Writes settings to a DOM element.

Subclasses should take care to call writeCommonProperties() to write common properties to the element.

See also
readXml()

Implements QgsAbstractTerrainSettings.
